Font Viewer

What Is Font Viewer?

Font Viewer is an online font preview tool that loads TTF, OTF, WOFF and WOFF2 files locally in your browser through the FontFace API, so you can check a font without uploading it anywhere. It renders sample text at six font sizes from 12px to 64px at once, making it easy to judge legibility and style across sizes.

Main Features

• Supports TTF, OTF, WOFF and WOFF2 font formats
• Previews a font at 12 / 16 / 24 / 36 / 48 / 64px simultaneously
• Custom sample text re-renders instantly as you type
• All processing happens locally in the browser; nothing is uploaded
• Shows the exact error message when a font fails to load

Use Cases / Notes

Great for choosing web fonts, comparing size hierarchies, or checking a font file before use. Older browsers without FontFace support cannot load fonts; use a recent version of Chrome, Edge or Firefox.

How to Use

1. Click “Choose font” and pick a TTF, OTF, WOFF or WOFF2 file
2. Enter the text you want to preview, or leave it blank for the default sample
3. Review the rendering at each size, and click “Clear” to try another font
